public class ACERReturnLevel extends ReturnLevel
Given an ACER function, compute the return level \(\eta\) for a given return period \(R\). \(\epsilon_k(\eta)\) can be computed as the inverse of this equation: \[ R = \frac{1}{Pr(X > \eta)} = \frac{1}{1 - \exp(-\epsilon_k(\eta) N)} \] and the corresponding return level \(\eta\) can be found by the inverse of the ACER function.
